guestrace

A whole-system system-call tracer for VM guests

Overview

Ryan Johnson began writing guestrace as a prototype for a research project. Since then, we have packaged guestrace as a stand-alone utility. A properly-configured guestrace will print as they occur the system calls which processes invoke within a guest host. The guestrace utility relies on libvmi to perform virtual-machine introspection.

Guestrace also provides a library, libguestrace, which gives programmers access to the guestrace engine. This is useful for programs which must trace system calls and do more than merely print them.

Details

Please refer to guestrace's API documentation for details about how to use the library.
